See full text

A lens exchange structure of spectacles is disclosed. The lens exchange structure comprises a lens frame, a lens, a pressing part, and an elastic part. A channel is disposed on the bottom of the lens frame. An intercalation hole is disposed on the inner side of the central nose bridge. The pressing part is inserted into the intercalation hole. The pressing part has hook parts and an accommodating groove for receiving the elastic part. One terminal of the elastic part is against the wall of the lens frame, and the lens has positioning holes for receiving the hook parts. Therefore, a pressing action may be used to compress or release the elastic part to let the hook parts correspondingly hook in or release from the positioning holes. The effect of easy lens assembling and exchanging as well as stable positioning can be accomplished.
